九、课程章节信息
9.1.模板和urls
拷贝course-comments.html 和 course-video.html放入 templates目录下
先改course-video.html，同样继承base.html，然后里面有属于自己的样式，也要保留
（1）配置url和视图
# 课程章节信息页
re_path('info/(?P<course_id>\d+)/', CourseInfoView.as_view(), name="course_info"),
class CourseInfoView(View):
'''课程章节信息'''
def get(self, request, course_id):
course = Course.objects.get(id=int(course_id))
return render(request, "course-video.html", {
"course": course,
})
（2）配置相关的链接
首先修改course-vedio.html中custom_bread里面的链接
{% block custom_bread %}
<section>
<div class="wp">
<div class="crumbs">
<ul>
<li><a href="index.html">首页</a>></li>
<li><a href="{% url 'course:course_list' %}">公开课程</a>></li>
<li><a href="{% url 'course:course_detail' course.id %}">课程详情</a>></li>
<li>章节信息</li>
</ul>
</div>

然后修改course-detetail.html中点“开始学习”的链接
<div class="btns">
<div class="btn colectgroupbtn" id="jsLeftBtn">
{% if has_fav_course %}已收藏{% else %}收藏{% endif %}
</div>
<div class="buy btn"><a style="color: white" href="{% url 'course:course_info' course.id %}">开始学习</a></div>
</div>
9.2.章节和视频
（1）给Vedio Model添加一个url字段
url = models.CharField('访问地址',default='',max_length=200)
class Video(models.Model):
lesson = models.ForeignKey(Lesson, verbose_name="章节",on_delete=models.CASCADE)
name = models.CharField("视频名",max_length=100)
url = models.CharField('访问地址',default='',max_length=200)
add_time = models.DateTimeField("添加时间", default=datetime.now)
class Meta:
verbose_name = "视频"
verbose_name_plural = verbose_name
def __str__(self):
return self.name
在xadmin后台添加课程章节和章节视频信息及链接
python-->>章节-->>视频
（2）给Course添加一个获取章节的方法
def get_course_lesson(self):
#获取课程的章节
return self.lesson_set.all()
class Course(models.Model):
'''课程'''
DEGREE_CHOICES = (
("cj", "初级"),
("zj", "中级"),
("gj", "高级")
)
name = models.CharField("课程名",max_length=50)
desc = models.CharField("课程描述",max_length=300)
detail = models.TextField("课程详情")
degree = models.CharField('难度',choices=DEGREE_CHOICES, max_length=2)
learn_times = models.IntegerField("学习时长(分钟数)",default=0)
students = models.IntegerField("学习人数",default=0)
fav_nums = models.IntegerField("收藏人数",default=0)
image = models.ImageField("封面图",upload_to="courses/%Y/%m",max_length=100)
click_nums = models.IntegerField("点击数",default=0)
tag = models.CharField('课程标签',default='',max_length=10)
add_time = models.DateTimeField("添加时间",default=datetime.now,)
course_org = models.ForeignKey(CourseOrg, on_delete=models.CASCADE, verbose_name="所属机构", null=True, blank=True)
category = models.CharField("课程类别",max_length=20, default="")
class Meta:
verbose_name = "课程"
verbose_name_plural = verbose_name
def get_zj_nums(self):
#获取课程的章节数
return self.lesson_set.all().count()
def get_course_lesson(self):
#获取课程的章节
return self.lesson_set.all()
def get_learn_users(self):
#获取这门课程的学习用户
return self.usercourse_set.all()[:5]
def __str__(self):
return self.name
（3）给Lesson添加一个获取所有视频的方法
def get_lesson_vedio(self):
#获取章节所有视频
return self.video_set.all()
class Lesson(models.Model):
'''课程章节'''
course = models.ForeignKey(Course,verbose_name='课程',on_delete=models.CASCADE)
name = models.CharField("章节名",max_length=100)
add_time = models.DateTimeField("添加时间",default=datetime.now)
class Meta:
verbose_name = "章节"
verbose_name_plural = verbose_name
def get_lesson_vedio(self):
#获取章节所有视频
return self.video_set.all()
def __str__(self):
return '《{0}》课程的章节 >> {1}'.format(self.course, self.name)
（4）给Vedio添加一个学习时长的字段
learn_times = models.IntegerField("学习时长(分钟数)",default=0)
class Video(models.Model):
'''章节视频'''
lesson = models.ForeignKey(Lesson, verbose_name="章节",on_delete=models.CASCADE)
name = models.CharField("视频名",max_length=100)
url = models.CharField('访问地址',default='',max_length=200)
learn_times = models.IntegerField("学习时长(分钟数)", default=0)
add_time = models.DateTimeField("添加时间", default=datetime.now)
class Meta:
verbose_name = "视频"
verbose_name_plural = verbose_name
def __str__(self):
return self.name
课程章节和视频
<div class="mod-chapters">
{% for lesson in course.get_course_lesson %}
<div class="chapter chapter-active" >
<h3>
<strong><i class="state-expand"></i>{{ lesson.name }}</strong>
</h3>
<ul class="video">
{% for vedio in lesson.get_lesson_vedio %}
<li>
<a target="_blank" href='{{ vedio.url }}' class="J-media-item studyvideo">{{ vedio.name }} ({{ vedio.learn_times }})
<i class="study-state"></i>
</a>
</li>
{% endfor %}
</ul>
</div>
{% endfor %}
</div>
9.3.资料下载
（1）在后端添加资源文件
（2）view中把当前课程的课程资源传到前端
class CourseInfoView(View):
def get(self,request,course_id):
course = Course.objects.get(id=int(course_id))
all_resources = CourseResource.objects.filter(course=course)
return render(request,'course-video.html',{'course':course,'all_resources':all_resources})
（3）前端页面显示
<div class="box mb40">
<h4>资料下载</h4>
<ul class="downlist">
{% for course_resource in all_resources %}
<li>
<span ><i class="aui-iconfont aui-icon-file"></i> {{ course_resource.name }}</span>
<a href="{{ MEDIA_URL }}{{ course_resource.download }}" class="downcode" target="_blank" download="" data-id="274" title="">下载</a>
</li>
{% endfor %}
</ul>
</div>
点下载可以下载我们在后端传上去的文件
把课程的信息也顺便改了
<div class="hd">
<h2 class="l">{{ course.name }}</h2>
</div>
<div class="statics clearfix">
<div class="static-item ">
<span class="meta-value"><strong>{{ course.get_degree_display }}</strong></span>
<span class="meta">难度</span>
<em></em>
</div>
<div class="static-item static-time">
<span class="meta-value">{{ course.learn_times }}分钟</span>
<span class="meta">时长</span>
<em></em>
</div>
<div class="static-item">
<span class="meta-value"><strong>{{ course.students }}</strong></span>
<span class="meta">学习人数</span>
<em></em>
</div>
</div>
9.4.讲师提示
（1）给Course添加一个teacher外键
teacher = models.ForeignKey(Teacher,verbose_name='讲师',null=True,blank=True,on_delete=models.CASCADE)
class Course(models.Model):
'''课程'''
DEGREE_CHOICES = (
("cj", "初级"),
("zj", "中级"),
("gj", "高级")
)
name = models.CharField("课程名",max_length=50)
desc = models.CharField("课程描述",max_length=300)
detail = models.TextField("课程详情")
degree = models.CharField('难度',choices=DEGREE_CHOICES, max_length=2)
learn_times = models.IntegerField("学习时长(分钟数)",default=0)
students = models.IntegerField("学习人数",default=0)
fav_nums = models.IntegerField("收藏人数",default=0)
image = models.ImageField("封面图",upload_to="courses/%Y/%m",max_length=100)
click_nums = models.IntegerField("点击数",default=0)
tag = models.CharField('课程标签',default='',max_length=10)
add_time = models.DateTimeField("添加时间",default=datetime.now,)
course_org = models.ForeignKey(CourseOrg, on_delete=models.CASCADE, verbose_name="所属机构", null=True, blank=True)
category = models.CharField("课程类别",max_length=20, default="")
teacher = models.ForeignKey(Teacher,verbose_name='讲师',null=True,blank=True,on_delete=models.CASCADE)
class Meta:
verbose_name = "课程"
verbose_name_plural = verbose_name
def get_zj_nums(self):
#获取课程的章节数
return self.lesson_set.all().count()
def get_course_lesson(self):
#获取课程所有章节
return self.lesson_set.all()
def get_learn_users(self):
#获取这门课程的学习用户
return self.usercourse_set.all()[:5]
def __str__(self):
return self.name
在后台为课程添加一个讲师
（2）给Course再添加两个字段 “课程须知”和“老师告诉你能学到什么”
youneed_know = models.CharField('课程须知',max_length=300,default='')
teacher_tell = models.CharField('老师告诉你',max_length=300,default='')
class Course(models.Model):
'''课程'''
DEGREE_CHOICES = (
("cj", "初级"),
("zj", "中级"),
("gj", "高级")
)
name = models.CharField("课程名",max_length=50)
desc = models.CharField("课程描述",max_length=300)
detail = models.TextField("课程详情")
degree = models.CharField('难度',choices=DEGREE_CHOICES, max_length=2)
learn_times = models.IntegerField("学习时长(分钟数)",default=0)
students = models.IntegerField("学习人数",default=0)
fav_nums = models.IntegerField("收藏人数",default=0)
image = models.ImageField("封面图",upload_to="courses/%Y/%m",max_length=100)
click_nums = models.IntegerField("点击数",default=0)
tag = models.CharField('课程标签',default='',max_length=10)
add_time = models.DateTimeField("添加时间",default=datetime.now,)
course_org = models.ForeignKey(CourseOrg, on_delete=models.CASCADE, verbose_name="所属机构", null=True, blank=True)
category = models.CharField("课程类别",max_length=20, default="")
teacher = models.ForeignKey(Teacher,verbose_name='讲师',null=True,blank=True,on_delete=models.CASCADE)
youneed_know = models.CharField('课程须知',max_length=300,default='')
teacher_tell = models.CharField('老师告诉你',max_length=300,default='')
class Meta:
verbose_name = "课程"
verbose_name_plural = verbose_name
def get_zj_nums(self):

return self.lesson_set.all()
def get_learn_users(self):
#获取这门课程的学习用户
return self.usercourse_set.all()[:5]
def __str__(self):
return self.name
（3）前端显示
<div class="box mb40">

<p class="cnt">你好。我在看7.3节 关于使用上下文管理的那个例子。关于telnetlib库使用的一些问题。 Telnet.read_until(expected, timeout=None) ;使用这个方法容易卡在输入登陆用户名的位置就不执行了。假如telnet到目标主机，如果提示符不是login ，就无法登陆吗？</p>

<p class="cnt">精品，老早就听医生的课了，这次的课程又让我长见识了，就像别的同学说的那样，如此简洁的实现酷炫动画的方式让我激动，赶快学完视频内容好去实现那10个任务，到时候希望徐大神好好指导指导我，如果学完后能给我个行业推荐啥的就更好了，明年就开始实习了！老紧张了--</p>
